Efecto del agua de mar como potenciador de crecimiento en potros ingles mestizo

Abstract

Due to the need to know the advantages of sea water as a growth promoter in English crossbred foals, the effect of the application of this element as a growth enhancer was evaluated. For the development of the research, a total of 12 animals were used, 3 replicates for each treatment in 3 experimental treatments corresponding to the application of purified sea water with different levels per treatment: T1 (50ml), T2 (100ml), and T3 (150ml) to compare them with a control (T0), the application of each dose was applied weekly during three consecutive weeks. For the evaluation of the research, a Completely Randomized Design (CRD) was applied. The results obtained from the present investigation were subjected to the ADEVA statistical analysis of variance, for the separation of means of the treatments the Duncan test was applied at a significance level of P<0.05. The results showed that for the parameters of growth evaluation, the best treatment was T3, which achieved better results in the parameters of height at withers, thoracic perimeter and body length, evidencing a better development of the animals used in the study. The costs of the research by treatment showed that the treatment with the highest cost was T3, which obtained a cost benefit of USD 1.31, that is to say that for each dollar invested there is a return of 0.31 dollars, followed by T2, which for each dollar invested has a return of 0.24 dollars, T1 has a cost benefit of 0.23 dollars, and finally the control is the treatment that presented the lowest cost benefit with a return of 0.18 dollars for each dollar invested.
